Europium is a chemical element; it has symbol Eu and atomic number 63. It is a silvery-white metal of the lanthanide series that reacts readily with air to form a dark oxide coating. Europium is the most chemically reactive, least dense, and softest of the lanthanides. It is soft enough to be cut with a knife.
Europium compounds fluoresce under UV light at 395 nm and 365 nm. [1] Europium compounds are compounds formed by the lanthanide metal europium (Eu). In these compounds, europium generally exhibits the +3 oxidation state, such as EuCl 3, Eu(NO 3) 3 and Eu(CH 3 COO) 3. Compounds with europium in the +2 oxidation state are also known.
EuFOD is the chemical compound with the formula Eu(OCC(CH 3) 3 CHCOC 3 F 7) 3, also called Eu(fod) 3. This coordination compound is used primarily as a shift reagent in NMR spectroscopy . It is the premier member of the lanthanide shift reagents and was popular in the 1970s and 1980s.
Europium(II) sulfide is the inorganic compound with the chemical formula EuS. It is a black, air-stable powder . Europium possesses an oxidation state of +II in europium sulfide, whereas the lanthanides exhibit a typical oxidation state of +III. [ 1 ]
Europium(III) chloride is an inorganic compound with the formula EuCl 3. The anhydrous compound is a yellow solid. Being hygroscopic it rapidly absorbs water to form ...

Europium(III) oxalate (Eu 2 (C 2 O 4) 3) is a chemical compound of europium and oxalic acid. There are different hydrates including the decahydrate, hexahydrate and tetrahydrate. [ 1 ] Europium(II) oxalate is also known.
Europium(III) oxide (Eu 2 O 3), is a chemical compound of europium and oxygen. It is widely used as a red or blue phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors. It is also an agent for the manufacture of fluorescent glass. Europium fluorescence is used in the anti-counterfeiting phosphors in ...
